Zikafikazida zomvera, amplifier imagwira ntchito yofunika kwambiri pozindikira kumveka bwino kwa makinawo. Mwa zambiri specifications kutifotokozani ntchito ya amplifier, kuyankha pafupipafupi ndi chimodzi mwazinthu zofunika kwambiri. Kumvetsetsa momwe ma frequency reaction range amakhudzirakhalidwe la mawuzitha kuthandiza ma audiophiles ndi omvera wamba kupanga zosankha mwanzeru posankha zida zomvera.

Kuyankha pafupipafupi ndi chiyani?

Kuyankha pafupipafupi kumatanthawuza kusiyanasiyana kwa ma frequency omwe amplifier imatha kupanganso bwino. Nthawi zambiri amayezedwa mu Hertz (Hz) ndipo amawonetsedwa ngati osiyanasiyana, monga 20 Hz mpaka 20 kHz. Mtunduwu umakhudza kuchuluka kwa ma frequency omwe amamveka kwa anthu ndipo nthawi zambiri amatengedwa kuti amachokera ku 20 Hz (mabasi otsika kwambiri) mpaka 20 kHz (matatu apamwamba kwambiri). Chokulitsa chomwe chimakhala ndi ma frequency ambiri oyankha chimatha kupanganso mawonekedwe ambiri, kuwongolera kwambiri kumvetsera.

Kufunika kwa Mayankho a pafupipafupi

1. Kubala kwa Bass: Kumapeto kwafupipafupi kwafupipafupi, komwe kumakhala pansi pa 100 Hz, ndi kumene ma bass amakhala. Amplifier yomwe imatha kuberekanso bwino ma frequency otsikawa imapangitsa kuti ikhale yolemera, yochulukirapokuzama kwamawu.Kwa mitundu yomwe imafunikirabass yakuya, monga zamagetsi, hip-hop, ndi nyimbo zachikale, amplifier yokhala ndi maulendo afupipafupi omwe amafika ku 20 Hz akhoza kusintha kwambiri khalidwe la mawu.

2. Kumveka Kwapakatikati: Mafupipafupi apakati (pafupifupi 300 Hz mpaka 3 kHz) ndi ofunika kwambiri pa kumveka bwino kwa mawu ndi mamvekedwe achilengedwe a zida. Amplifier yomwe imapambana mumtunduwu imatsimikizira kuti mawu ndi zidakumveka bwinondi moyo. Ngati kuyankha pafupipafupi kumakhala kochepa pamtunduwu, phokoso lidzakhala lamatope komanso losamveka bwino, zomwe zimakhudza kumvetsera kwathunthu.

3.Treble Tsatanetsatane: Ma frequency apamwamba, makamaka omwe ali pamwamba pa 3 kHz, amathandizira mwatsatanetsatane komanso kumveka bwino kwa mawu. Zoimbira monga zinganga, zitoliro, ndi violin zimamveka motere. Amplifier yomwe imatha kutulutsanso ma frequency awa imatha kupereka malo ndi tsatanetsatane, kuwongolera kumveka bwino kwa mawu. Kusayankha pafupipafupi kokwanira mumtundu wa treble kumatha kupangitsa kuti zisamveke bwino kapenaphokoso lopanda moyo.

Momwe kuyankha pafupipafupi kumakhudzira mtundu wamawu

Kuyankha kwafupipafupi kwa amplifier kumakhudza momwe amapangira mitundu yosiyanasiyana yazizindikiro zomvera.Nazi zina mwa njira zazikulu zomwe kuyankha pafupipafupi kumakhudzira mtundu wamawu:

1. Kupotoza ndi mitundu: Ngati chokulitsa mawu sichingathe kutulutsanso ma frequency amtundu wina, chingapangitse kuti mawuwo asokonezeke kapena asinthe mitundu. Mwachitsanzo, ngati amplifier sangathe kugwira bwino ma frequency otsika, imatha kutulutsa mabass opotoka omwe samamveka bwino. Kusokoneza uku kumawonekera makamaka m'magawo ovuta momwe zida zingapo zikusewera nthawi imodzi.

2. Dynamic Range: Andynamic range ya amplifieramatanthauza kusiyana pakati pa voliyumu yabata kwambiri ndi yaphokoso kwambiri yomwe imatha kupanganso. Kuyankha kwapang'onopang'ono kumatanthawuza kusinthasintha kokulirapo, komwe kumalola chokulitsa kuti chizitha kuthana ndi zowoneka bwino komanso ma crescendo amphamvu popanda kupotoza. Kutha kumeneku ndikofunikira kwambiri pamitundu yomwe imadalira kusiyanitsa kwamphamvu, monga nyimbo zachikale ndi jazi.

3. Mayankho a Gawo: Kuyankha pafupipafupi sikumangotanthauza kukula kwa mawu pama frequency osiyanasiyana, komanso kumakhudzanso kuyankha kwa gawo, yomwe ndi nthawi yamafunde amphamvu. Ma Amplifiers omwe ali ndi gawo lopanda kuyankha angayambitse vuto la nthawi, kupangitsa kuti phokoso likhale losagwirizana kapena kusalunzanitsidwa. Izi ndizowononga makamaka pakukhazikitsa stereo, komwe kujambula kolondola ndi gawo lamawu ndikofunikira pakupangakumvetsera mozama.

4. Kugwirizana ndi okamba: Kuyankha pafupipafupi kwa amplifier kuyeneranso kugwirizana ndi okamba omwe amayendetsa. Ngati amplifier ili ndi kuyankha kwafupipafupi, sikungagwiritse ntchito bwino ntchito ya wokamba nkhani wapamwamba. Mosiyana ndi zimenezi, amplifier yapamwamba yokhala ndi mayankho ochuluka afupipafupi amatha kugwiritsa ntchito bwino ntchito ya wokamba nkhaniyo mpaka momwe angathere.

Kusankha Amplifier Yoyenera

Litikusankha amplifier, ndikofunikira kulingalira kuchuluka kwa kuyankha pafupipafupi limodzi ndi zina monga kupotoza kwathunthu kwa harmonic (THD), chiŵerengero cha signal-to-noise (SNR), ndi kutulutsa mphamvu. Amplifier yochita bwino sikuti imangoyankha pafupipafupi komanso imasokoneza pang'ono komansokutulutsa mphamvu zambirikuyendetsa bwino okamba.

Kwa ma audiophiles, tikulimbikitsidwa kumvera zokulitsa zosiyanasiyana m'malo olamuliridwa kuti muwone momwe akumvera. Samalani momwe amplifier amapangiranso ma bass, apakati, ndi ma treble frequency. Amplifier yabwino iyenera kupereka mawu omveka pamitundu yonse ya ma frequency, zomwe zimapangitsa kumvetsera kosangalatsa.

Pomaliza

Mwachidule, kuyankha pafupipafupi kwa amplifier ndi chinthu chofunikira kwambiri chomwe chimakhudza kwambiri mtundu wamawu. Kuyankha kwafupipafupi kumalola kutulutsa bwino kwa bass, kumveka bwino kwapakati, ndi tsatanetsatane wa katatu, zonse zomwe zimathandizira kumvetsera mozama komanso kosangalatsa. Pomvetsetsa kufunikira kwa kuyankha pafupipafupi, ogula amatha kupanga zisankho zodziwikiratu posankha ma amplifiers, kuwonetsetsa kuti amapeza mawu abwino kwambiri pamawu awo. Kaya ndinu ongomvetsera mwachisawawa kapena mumangomvetsera mwachidwi, kulabadira kuyankha pafupipafupi kungakupangitseni kuti mumve zambiri.
